SPECIFICATION forming part of Letters IatentNo. 224,162, dated February 3, 1880.

' Application filed September 121879.

To all whom may concern:

Be it known that we, CHARLES N. FISHER, of the town of Willis, Montgomery county, and

State of Texas, (a native of Great Britaim) and CHARLES LL DOWNEs'Of Jersey City, in the county of Hudson and State of NewJersey, have invented new and useful Improvements in Fountain-Pensyand we do hereby declare of our improved stylographic fountain -pen.

Fig. 2 is a diametrical section through the pen, greatly enlarged. Figs. 3 and 4 are enlarged sectional details.

Similar letters of reference indicate corresponding parts.

This invention relates to stylographic foun rain-pens wherein the ink is caused to flow from a reservoir in the handle of the pen, in the act of writing, through a conical writingpoint having a very fine tapered bore.

The nature of our invention consists in combining with a reservoir-handle having a tubular writing-point and a long clearing-needle therefor an outer movable case or holder, a packing at the upper end thereof, a valve, and a spring,. as will be hereinafter explained, whereby,in the act ofwriting, air will be ad-' mitted into the ink-reservoir and the ink caused to flow freely from the point of the pen.

The invention also consists in adapting the case or holder, when it is detached from. the

valve-stem at the top of the reservoir-tube, to

serve as a means for allowing a person to fill thereservoir-tube with ink by pumping the same therein, as will be hereinafter explained.

In the annexed drawings, A designates the tube which forms the ink-reservoir, which tube may be'made of hardened rubber or of any other suitable material, and which may be made of one or two sections. To'the lower end of this tube A a writingpoirit, O, is secured. which is tipped with the most durable metal or other substance that will answer the purpose. The bore of this point is tapering for the smaller end of a long needle-clearer to work in, for the purpose of keepin g the bore open and free from the accumulation of sediment. I Q The upper end of the needle Gris flexibly attached at e to a tubular stem, 0, ot' a valve, 12. This valve 1) has its seat against the loweriend of aplug, E, which is secured into the upper end of the reservoir-tube A, and through which the prismatic portion. 0 passes freely. The

as to fit, loosely inside of a tubular holder or case, B. 1

Between the head of the tubular plug F and apacking, g, a spring, 8, is compressed and coiled around the valve-stem c. The packing g is confined on. the screw-threaded portion of the valve-stem 0, between two metal collars, on

stem 0 passes through the top of the holder or case B, and receives a nut or screw-cap, E, on it, which firmly unites the stem of valve 12 to the top of holder-B, but allows a'longitudinal movement of this holder and the tube Aon eachother.

By grasping the holder B (the tube A being supplied with ink) and performing the movements of writing, a motion will be imparted to the tubes A and B which will cause the valve b to be frequently opened and shut and air to be admitted in sufficient quantities into the reservoir-tubeA to maintain a free supply of ink from the writing-point. The spring 8 closes the valve 1) when pressure is removed from the holder B.

Air is admitted between parts A and B to the space above the partA, and when part B is pressed down thevalve b is opened to allow air to flow into the partA above the ink there in. When the pressure is removed from part B thesprin g s will close the valve 1). Thus it will be seen that during the actof writing the upper end of the part A is open-to admit air intotitr v To fill the reservoir-tube 'A, the nut E is reinoved from the valve-stem 0, the point 0 is introduced into a vessel of ink, and the holder B moved up and down quickly. At each up- Ward stroke of the holderB the finger should be pressed over. the hole through its upper head or upper end of plug F is enlarged, so

n,'aud this screw-threaded portion of valvee from said hole.

end, and during each downward stroke given to the holder the finger should be removed In this way ink can be pumped into the reservoir.

After supplying the reservoir with ink, and before commencing to write with the pen, the nut E should be screwed tightly on the valvestem 0, as shown in Fig. 2.

The extension a on the nut E is intended to receive the point-cap a when this cap is removed t'roin the point 0.

Although we have shown and described a construction in which the air to .be admitted to the ink-reservoir is conveyed through a passage between the two walls of the handle, yet we do not lay claim to this feature, as we are aware that pen-handles having double walls with airpassages between them have been used by others before our invention.

What we claim as new and as our invention is- CHARLES NICHOLAS FISHER. CHARLES L. DOWNES.
